when 0.684 g of an organic compound containing only carbon, hydrogen, and oxygen was burned in oxygen, 1.312 g of Co2 and 0.805 g of H2O were obtained. What is the empirical formula of the compound

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.

The answer is accuracy

Not a  mixture of two common elements that can be separated by physical means.
